2020-01-25	IB/mlx5: Return the administrative GUID if exists	Danit Goldberg
	A user can change the operational GUID (a.k.a affective GUID) through link/infiniband. Therefore it is preferred to return the currently set GUID if it exists instead of the operational. This way the PF can query which VF GUID will be set in the next bind. In order to align with MAC address, zero is returned if administrative GUID is not set. For example, before setting administrative GUID: $ ip link show ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 00:00:00:00:00:00:00:00, PORT_GUID 00:00:00:00:00:00:00:00, link-state auto, trust off, query_rss off Then: $ ip link set ib0 vf 0 node_guid 11:00:af:21:cb:05:11:00 $ ip link set ib0 vf 0 port_guid 22:11:af:21:cb:05:11:00 After setting administrative GUID: $ ip link show ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 11:00:af:21:cb:05:11:00, PORT_GUID 22:11:af:21:cb:05:11:00, link-state auto, trust off, query_rss off Fixes: 9c0015ef0928 ("IB/mlx5: Implement callbacks for getting VFs GUID attributes") Link: https://lore.kernel.org/r/20200116120048.12744-1-leon@kernel.org Signed-off-by: Danit Goldberg <danitg@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

	Implement the IB defined callback mlx5_ib_get_vf_guid used to query FW for VFs attributes and return node and port GUIDs. Signed-off-by: Danit Goldberg <danitg@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com>
2017-07-24	IB/mlx5: Restore IB guid/policy for virtual functions	Bodong Wang
	When a user sets port_guid, node_guid or policy of an IB virtual function, save this information in "struct mlx5_vf_context". This information will be restored later when pci_resume is called. To make sure this works, one can use aer-inject to generate PCI errors on mlx5 devices and verify if relevant fields are restored after PCI resume.

2016-03-21	IB/mlx5: Implement callbacks for manipulating VFs	Eli Cohen
	Implement the IB defined callbacks used to manipulate the policy for the link state, set GUIDs or get statistics information. This functionality is added into a new file that will be used to add any SRIOV related functionality to the mlx5 IB layer. The following callbacks have been added: mlx5_ib_get_vf_config mlx5_ib_set_vf_link_state mlx5_ib_get_vf_stats mlx5_ib_set_vf_guid In addition, publish whether this device is based on a virtual function. In mlx5 supported devices, virtual functions are implemented as vHCAs. vHCAs have their own QP number space so it is possible that two vHCAs will use a QP with the same number at the same time.
